WESPC Valve Guide 3343J002 For Perkins 4.236 4.248 6.354.2 A4.236 T4.236 6.354 6.354.1

Application:

This exhaust-valve guide is manufactured for the Perkins 4.236, 4.248, 6.354.2, A4.236, T4.236, 6.354, 6.354.1, 6.354.4, AT6.354, G4.236 and 1004-4, 1004-4T naturally aspirated and turbo-charged diesels, which means it is found in Massey Ferguson 165-398 series tractors, 30-50 industrial loaders, 550-890 combines, Landini 7860-8880 row-crop tractors, Claas 65-75 forage harvesters, JCB 3CX/4CX back-hoes, New Holland 1116 swathers, 1495/1496 mower-conditioners, Volvo BM 2200 forklifts, FG-Wilson P100-4 and P135-4 generator sets and a broad spread of irrigation, construction and marine auxiliaries that use the above engine families world-wide.

Technical specifications:

The guide is machined from centrifugally cast pearlitic cast-iron to an outside diameter of 15.9 mm, inside diameter 9.52 mm and an overall length of 61 mm; the bore is micro-honed to Ra 0.4 µm to give the valve stem a consistent 0.04-0.06 mm running clearance that prevents side-thrust wear while still allowing adequate oil film for cooling.

Material & performance features:

The iron matrix is alloyed with 0.7 % Cr and 0.3 % Mo to raise thermal conductivity and creep resistance, then salt-bath nitrided to give a 0.02 mm compound layer > 650 HV that resists scuffing and micro-welding when exhaust gas temperature exceeds 650 °C; the outside diameter is finished to h6 tolerance so the guide can be press-fitted into the cylinder head without additional reaming, while the chamfered bottom lip aids assembly and prevents bore distortion.
